Data Link Layer Address Masking

Data Link Layer Address Masking

The data link address masking helps to reduce the number of L2 address match
conditions.

For example, if you specify dlDstMask to be ffff.0000.0000, and if
dlDst is abcd.0000.0000, all traffic with the destination MAC address
that starts with abcd will be matched, regardless of the value of the
least significant 32 bits.
